Upgrade a domain that consists of multiple instances of
BlackBerry UEM

If the recommended upgrade path is to upgrade
UEM
versions in stages, then you must upgrade all instances to the first stage, restart them, and upgrade them all to the second stage. For example, if you are running
UEM
version 12.11, you must upgrade all instances by two
UEM
versions at a time to the latest
UEM
version.
If you’re upgrading your environment in stages, test your environment after each stage of the upgrade to make sure everything is working as expected. If it is not, resolve any issues before proceeding to the next stage of the upgrade.
  1. If the upgrade path is from
    BlackBerry UEM
    version 12.9.1 or earlier, shut down all instances of
    UEM
    in the domain.
  2. Upgrade one
    UEM
    core instance.
    The setup application also backs up and upgrades the
    UEM
    database. After the upgrade, the
    UEM
    instance starts automatically.
    When you upgrade a core instance, you must use an upgraded management console instance to connect to that core and manage the domain.
  3. Upgrade the other
    UEM
    core or management console instances. You can upgrade these remaining
    UEM
    instances more than one at a time.
  4. Upgrade any
    BlackBerry Connectivity Node
    -only instances (that contain only the device connectivity components) last. You can upgrade more than one
    BlackBerry Connectivity Node
    -only instance at a time.
